Title: Coolant types
Post by: Jimbob on 11 May 2009, 08:51:04

Just been looking in TIS at coolant - for a vectra issue, not mine...

It states you must
Blue / Green pre 2001
Pink / Red post 2001

the 2 must not be mixed.

The omega section says the same, but not in so harsh words.

I know we all use the red regardless of age, so will do the same on the vectra when I change it.


But why is TIS so insistant on the age separation?

Because that is around the time they changed the coolant type.....and at that time the red didn't mix well

Pretty certain the current Vx Red mixes OK?

I know the earlier reds, not just GMs, didn't mix...

So, has there been an official anouncement that red is fine to use in all?  and is mixable?

applying common sense, never good I know....


I would expect the blue to be discontinued, the red to superceed it, and an announcement that all cars to now use the red.

Aftermarket types (i.e. Halfords) state that the red antifreeze can be used in all types of engine, including alloy.  

The difference is in the corrosion inhibitor, not the antifreeze itself, which I'm sure is ethylene glycol in both types.

The problem is mixing certain types of red with certain types of blue.  not so much of an issue now, and besides, we'd do a thorough flush before swapping, wouldn't we ;)
